The article explores framing of the siting process of a deep geological repository of nuclear waste in the Czech Republic by the municipalities’ representatives in the pre-selected localities. Three distinguished frames have been reconstructed. The risk frame, which connects the project with a number of predominantly environmental threats, is counter-balanced by the responsibility frame that uses the ‘Not-In-My-Back-Yard’ label to delegitimize the local opposition. The third frame then portrays the siting process as a display of general distrust towards political elites and state institutions. It is argued that the distinguished frames stem from a deeper ideological conflict about the nature of democratic governance and the value attributed to environment, further stressing the importance of a siting process’ institutional arrangement that goes beyond technocratic solutions.
